Why I can't create 5GHz access point if firmware support 2.4GHz and 5GHz antenas and hostapd configured on create 5GHz?

With 2.4GHz I haven't this problem:

~ # iw dev wlan0 info
Interface wlan0
        ifindex 3
        wdev 0x1
        addr 54:4a:16:12:d0:64

        channel 11 (2462 MHz), width: 20 MHz, center1: 2462 MHz

~ # cat /etc/hostapd.conf

wpa_pairwise=TKIP CCMP
bridge=br0
ssid=STC-MT_TestWLAN
channel=11
wpa_passphrase=RnD777777

But I havn't double channel with if I add ht_capab=[HT40-] to hostapd.conf

Thank you and excuse my bad english.

hi , pls do the following and let us know the output
cd /usr/share/wl18xx
./ap_start.sh
( this script uses /usr/share/wl18xx/hostapd.conf by default )

Unfortunately I can't found ap_start.sh, I build all components from source.

Yes, this is probably the same issue.
Try typing:
COUNTRY=RU crda

and see if you get an error.
In case you do, you are probably missing the crda/regulatory.bin components in your file system.

Hello, Eyal!

I build CRDA from source, I clone sources from git, unfortunately CRDA always exit with error -1

Configuration wl1837 module into 5GHz as soft AP.

siva ch61 siva ch61

Hi All,

I am trying to configure the Wlink Wl1873 module into AP mode using the 5GHz band.

Here when I try to start the hostapd with the below configuration into 5GHz band. Its creating the error to start AP functionality.

hw_mode=a

channel=36,

ht_capab=[HT40+]

country_code=US

Error log saying that the hardware does not support to operate into 5Hz. I am copied the error log of hostapd with debug enabled for your reference.

Please check and suggest me how do I can configure the module into 5Hz.

Hi,

Seems like your regulatory seetings are not right. Do you have crda installed and working correcly?

What is the output of:

iw wlan0 reg get

iw wlan0 res set US

Hi Eyal,

Thanks for your quick response.

I tried the above commands to change regulatory domain and it's not success at our side.

I have started crda monitor "udevadm monitor --environment kernel" to debug this. From this log I have observed that domain is not configuring. I am attaching the log for your reference.

Please have a look and provide us the inputs to avoid this issue.

Seems like you don't have crda installed and country remains 00 (world).

This is why the AP is failing for you.

If it was working you should have seen something like:

In reply to Eyal Reizer:

Hi Eyal,

I would like to understand, Do I need to install CRDA explicitly?

Here I am using the wlbuild utils to generate the TI wireless drivers modules along with MAC and CFG80211.

As per my understanding CRDA is part of CFG80211 module and no need to install separately.

Is there any configurations need to be done in the CFG80211 to enable CRDA functionality support?

Please help me to resolve this issue.

Thanks & Regards

Ch. Siva

In reply to siva ch61:

Hi Siva,

CRDA is a user space agent that needs to be built/installed separately.

See:

drvbp1.linux-foundation.org/.../

Had you used our build script:

processors.wiki.ti.com/.../WL18xx_System_Build_Scripts

crda is one of the components that are built when using it alongside libnl, wpa_supplicant, hostapd etc.:

processors.wiki.ti.com/.../WL18xx_System_Build_Scripts

Hi Eyal,

Thank you for the inputs.

When I run the command "COUNTRY=US crda" I am getting below error.

"failed to open db file: No such file or directory"

It would help me, if you provide us the procedure to enable CRDA on TI platform.

I appreciate your support on this.

Thanks & Regards

In reply to siva ch61:

Hi,

You are probably missing the regulatory.bin database in your file system:

wireless.wiki.kernel.org/.../wireless-regdb

This is a generic mechanism for regulatory domain in linux and is not related at all to TI platform or any other platform.

You can try getting it manually from the git described in the link above and install it into your target fileystem.

Again. if you would have used the build script for building crda, it would have installed it all for you.

processors.wiki.ti.com/.../WL18xx_System_Build_Scripts

Hi Eyal,

Thanks for your inputs.

I have copied all the required binaries and libraries and able to configure into 5GHz mode on target platform.

The below are the procedure to configure WL18xx modules into 5GHz operating mode. It would help people how are facing difficultly in change of band.

1. Create file "regulatory.rules" under "/etc/udev/rules.d/" add the below content to interact CRDA with kernel spcace to change regulatory domain.

KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform", RUN+="/sbin/crda"

2. Copy the crda binaries which is generated part of WL18xx_System_Build into "/sbin" of target system.

$cp crda /sbin/

$cp libcrda.so /usr/lib/

3. copy the Public certificates into "/etc/wireless-regdb/pubkeys"

3. copy the regulatory domain binary file into "/usr/lib/crda/regulatory.bin"

4. run the commands to set regulatory domain

iw reg get

iw reg set US

iw reg get

Hello Eyal!
Yes, I make all steps except udev because all drivers embedded in linux, I use mdev instead udev.

Ok, I think I solve this problem after copy db.txt to linux/net/wireless/db.txt and enable CONFIG_CFG80211_INTERNAL_REGDB

0 Eyal Reizer over 8 years ago in reply to Anatoly Barinov

TI__Mastermind 20285 points

INTERNAL_REGDB is not really recommanded as it works without crda and doesnt allow to to chane regulatory regions without rebuilding the kernel.

Anyway it is your decision.

Yes, you right, but I can't now solve problem with crda.
